US Department of Energy continues to fund dimethyl ether



SAN DIEGO, Nov. 04, 2021 (GLOBE NEWSWIRE) – The Vehicle Technologies Office (VTO) of the United States Department of Energy (DOE) has awarded more than $ 4 million in funding to test new applications of ether dimethyl (DME) as a low carbon alternative to fossil fuels. Oberon Fuels, the first company to produce renewable DME (rDME) in the United States, is a supporting partner.

Funded projects include:

  • University of Wisconsin Madison for “Blending Efficiency and Controlled Compression Ignition Combustion of DME Propane Blends”
  • WM International Engineering LLC in Darrien, Illinois, for a project entitled “High Pressure Fast Response Direct Injection System for Liquified Gas Fuels Use in Light-Duty Engines”

“This new round of funding for the EMR builds on its June 2021 award and constitutes the continued validation of renewable EMR as an enabling molecule to decarbonize transportation,” said Rebecca Boudreaux, Ph.D., President and Chief from the management of Oberon Fuels. “Oberon Fuels generates value from waste, creates family jobs in rural areas and reduces both pollution and greenhouse gas emissions with our rDME. We are honored to partner with the recipients of the DOE Awards.

Funding was provided through the “Funding Opportunity Announcement for Research, Development, Demonstration and Deployment of Low-GHG Vehicle Technologies” to research, develop and validate technologies that use DME to increase the efficiency of direct injection engines. The partners will use the funding to develop new technologies to provide efficient engine operations with near-zero emissions, which is a win-win solution for consumers and the environment.

Renewable DME dramatically reduces emissions and carbon intensity when used in place of traditional fuels in three applications: as a blending agent with liquefied petroleum gas (LPG or propane); as a replacement for diesel in compression ignition engines; and as an economical and energy-dense way to transport and store renewable hydrogen. When produced using the Oberon process, the California Air Resources Board has calculated that rDME made from dairy biogas has an estimated carbon intensity (CI) value of -278 compared to ultra-low diesel. sulfur which has an IC of about 100 gCO2e / MJ. Renewable DME used as a transportation fuel can decarbonize the transportation sector while significantly reducing emissions of particulates, greenhouse gases and other pollutants.

Founded in 2010 to provide innovative energy solutions to reduce emissions, waste and carbon impact, Oberon Fuels is the only company currently producing commercially renewable DME. Beyond cleaner emissions, the Oberon Fuels process rDME creates economic opportunities and jobs for rural economies by linking waste raw materials to multiple renewable fuel markets.

About Oberon Fuels
California-based Oberon Fuels has a global mission to decarbonize the fuel and energy industries through the commercialization of a powerful and enabling molecule: dimethyl ether (DME). Renewable DME can dramatically reduce industrial emissions by replacing fossil fuel-based incumbents: as an energy-dense, cost-effective way to displace renewable hydrogen; as a mixing agent for LPG; and as a replacement for diesel. Oberon continues to challenge the status quo by introducing innovative solutions that reduce emissions, improve local air quality and create economic opportunities for communities. In 2013, the Oberon Fuels refinery in Brawley, California produced the first fuel-grade DME in North America, and in 2021 produced the very first renewable DME in the United States. Oberon’s DME has powered vehicle demonstrations around the world with Volvo Trucks, Mack Trucks, Ford, among others. Founded in 2010, Oberon Fuels is a privately held company owned by private and strategic investors, including Suburban Propane Partners, LP (NYSE: SPH).
